Answer:
The 8-hour time-weighted average (TWA) exposure limit for hydrogen sulfide is 20 parts per million (ppm), and the short-term exposure limit (STEL) is 50 ppm over a 15-minute period.
Step-by-step explanation:
Hydrogen sulfide (H2S) is a highly toxic and dangerous gas. The minimum lethal dose of hydrogen sulfide can vary depending on several factors, such as an individual's health, duration of exposure, and environmental conditions. However, even very low concentrations of hydrogen sulfide can be lethal.
Inhalation of even small amounts of hydrogen sulfide can cause various health effects, including respiratory irritation, dizziness, nausea, headaches, and eye irritation. At higher concentrations, it can lead to loss of consciousness, respiratory failure, and death.I hope this helped!
